The aim of this report is to give the reader insight into the development of theweb-based accounting application SuperBooky. Accounting is a complex task thatmany beginner entrepreneurs struggle with. The development of this application wastherefore focused on making accounting as convenient and as easy as possible. Theend product targets small enterprises and its functionality was designed with this inmind.To make sure that the application was designed in a user-friendly way, polls werecarried out among individuals with basic accounting knowledge. These polls werethen used as a basis when the application was under development, to ensure that itwas well-suited to the target audience.This project was carried out as a bachelor?s thesis for Chalmers University of Technologyand University of Gothenburg during Spring 2015.

AbstractAs a developer of database-driven applications you will be faced with difficult choices, when it comes to choosing database, server and programming language. For the result to be satisfactory it requires the different techniques to interact well with each other and also fulfill performance expectations. This is even more important when the application is deployed to the cloud and the response time plays a major role.This paper evaluates different databases and their performance. To test the databases there was an application made in the server script language PHP or Hypertext Preprocessor and it was deployed to Windows Azure cloud platform. The test applications task is to call and load databases by controlled requests which creates, reads, updates and deletes data in an relatively large extent.The results shows that locale databases or databases in the same data center as the server generates the fastest response.

In today?s society computers are getting a much more important role. To get a computer to work as intended it has to be programmed. A computer program is written with programming languages. There is an abundance of programming languages available today and there are many differences and similarities between them. The different languages have their advantages and their disadvantages where some of them are intended for fast performance, some to be cheap on memory usage, and some are developed to be easy to program on. In our thesis we have chosen to compare four of todays most common languages, C, C++, Java and Python.

Denna rapport ämnar beskriva framtagningen av en applikation för Android riktad mot aktiva inom ridsporten. Under många tävlingar inom ridsporten har tävlande och åskådare svårt att snabbt få tillgång till resultaten på plats. Projektet ämnar öka tillgängligheten till resultat och startlistor, vilket resulterade i en prototypapplikation för Android.Rapporten beskriver hur det i början av projektet genomfördes en förstudie där projektgruppen tittade närmare på Equipe AB:s webbtjänster samt skapade en öppen marknadsundersökning som låg till grund för utvecklingen av applikationen. Rapporten tar även upp projektets utvecklingsprocess, Scrum. Efter färdigställande av en prototyp av applikationen genomfördes användartester för att utvärdera de olika delarna och samla data inför vidare utveckling.I rapporten beskrivs prototypen, där basfunktionerna är presentation av start och resultatlistor, onlinelistor, bevakning av en start och lista alla aktuella tävlingar med respektive tidschema.

What is creativity? Why is it important? How can you stimulate pupils to becomemore creative? These are some of the questions that are studied in this thesis.The discussion is focused on programming as the medium of creativity and theresult is a setup for a course book that teaches programming at the same time asit makes the reader more creative. The results are based on literature study aswell as observations and interviews with teachers and pupils from three differentschools in Stockholm, Sweden. The study shows that gets more important everyday as more and more jobs are replaced by computers and we live in an age ofabundance. The teachers would like the pupils to be more creative but don?tknow how achieve that at the same time as they have to teach them everythingthat they are supposed to know when the course ends..

This paper is about the new programming language from Microsoft, C# (See Sharp) and the .NET Framework. They are still in beta-version, but will be released on the market in February 2002. This paper presents C#, not in detail but the characteristics that distinguish the language. A comparison is done with C++ and Java, since C# is most resembling to these languages. Both C# and Java have been developed from the mother- language C++.

Vi har i detta arbete skapat ett API för widgets på Android och iOS för Visiarcs utvecklingsverktyg CoffeeMaker. CoffeeMaker använder sig av multiplattform-API:t Cocos2dx och försöker, i så stor utsträckning det är möjligt, förhålla sig till det reaktiva programmeringsparadigmet. Vi använde oss av olika designmönster för att jämna ut skillnaderna mellan Android och iOS interface och implementerade funktionalitet för knappar, checkboxes, radioknappar och textfält på dessa två plattformar. Dessa widgets tematiseras enligt ett JSON-liknande format och använder sig av en texturatlas för att spara resurser. Vi behövde en texturpackare som lämpade sig att köras under en applikations initiering och ibland även under själva körningen.

The purpose of this thesis is to develop an application for mobile phones that simplifies communication. The company Doberman wanted to look at possibilities to develop such an application that uses Bluetooth? technol-ogy to communicate in ad-hoc networks. The aim has been an application to run on mobile phones in which you can send messages and files to other devices and also add a user profile with personal information to share with others. The communication will take place in temporary networks created when Bluetooth enabled devices is in range of each other.The market for mobile phones has grown rapidly over the past years and is still growing.

This thesis is about making a support for barcode readers and RFID readers on a computermounted in heavy vehicles. The computer has several applications designed for heavyvehicles such as an order handling application. The goal was to suggest an architecture toimplement a support for the readers. The architecture should be independent of whichmanufacturer who has made the reader hardware that was connected to the computer.At first a theoretically study was made around RFID technology and standards for thetransport and supply sector. Then the architecture was developed and a demo implementationwas made.The conclusion of this thesis is to implement support for barcode readers with a wedgeapplication.

In this report we compare the two programming languages PHP and C# in .Net. They are both used to create dynamic websites and on the web there's a debate going on about which of these languages you're recommended to use. With this report we want to make ourselves a more scientific base of which of these languages that is the most used language and which languages that are the most suitable for creating dynamic websites. We have two purposes with this report:1. To compare the usage of the programming languages C# in .Net and PHP at web agencies, advertising agencies and combinded agencies in Sweden today.2.

Datormobiler (smartphones) har blivit ett populärt fenomen bland mobilanvändare. Det har dykt upp ett flertal stora aktörer på marknaden och i takt med att fler smartphones har utvecklats har också intresset för applikationsutveckling blivit större. En av dessa aktörer är Apple som idag har en betydande marknadsandel efter lanseringen av iPhone. Dock har Google tillsammans med Open Handset Alliance blivit en betydande konkurrent med deras mobila plattform Android.Syftet med denna uppsats är att göra en jämförande studie av applikationsutveckling för dessa plattformar. I detta ingår att undersöka plattformarnas programmeringsspråk med tillhörande aspekter, utvecklingsmiljöer, krav på utvecklaren och de ekonomiska aspekter som hör till utveckling och publicering.

In this project an iPhone application for storing food and drink experiences was developed with focus on an easy interaction design. The already existing market of similar applications were studied and evaluated to extract their positive and negative features. Interviews with experts within the food and drink business where made in the pre study to get a good perception of how to divide and categorize the sections in the application. To optimize the usability, workshops with potential users with different technical experiences where continuously held during the development of the design.During the development two variants of development environments where evaluated. The final result of the application was developed in the environment that made the best impression and seemed to be the best alternative.The resulting product has a thought out design meant to be easy to understand, even for the first time users.

Context. Performance and resource usage is often an important factor for database driven services. Depending on the purpose of the application, choosing the wrong type of database may require unnecessary hardware upgrades or replacements. Objectives. This study investigates the differences in performance and resource usage between different SQL- and NoSQL-databases.

This paper describes Tempus Custode, a smartphone application with which the user may register working hours and travel time during the work day. The application communicates with a database via a server. The data stored in the database may be manipulated using an administrator tool, mainly for the composition of time reports. In this way, the user?s task of time reporting his day is greatly simplified.The application is able to automatically discriminate between work time and travel time, as it continuously fetches positioning data from the smartphone GPS receiver.
